go ahead，talk to your dog.
as many a dog owner will prove, our furry friends are listening.now, for the doubters, there is scientific proof that theyunderstand much of what they hear. a border collie called rico canfetch at least 200 objects by name， researchers in germany say. thedog also appears to learn words for new objects as easily as a3-year-old child would. its word-learning skill is as good as thatof a parrot or chimpanzee.
in one experiment, the researchers took all 200 items that rico issupposed to know and divided them randomly into 20 sets of 10objects each. the dog waited with one of his owners in one room,while an experimenter put a set of 10 objects into another room.then, the owner told the dog to fetch one of the items. the dog hadto go to the other room and bring the object back.
in four trials, rico got 37 out of 40 commands right. because thedog couldn't see anyone to get visual clues about what to bringback, the scientists concluded that he must understand the meaningsof certain words.
in another experiment, the scientists took one toy that rico hadnever seen before and put it in a room with seven toys whose nameshe already knew. the dog's owner then told him to fetch the object,using a word rico had never heard.
